- Q1. What are valves and their functions
- Ans.
Valves are mechanical devices that control the flow of fluids or gases by opening, closing, or partially obstructing various passageways.
Valves are used in various industries such as oil and gas, water treatment, pharmaceuticals, and more.
They can be operated manually or automatically.
Valves can regulate the flow rate, pressure, temperature, and direction of fluids or gases.
Examples of valves include ball valves, gate
- Q2. Materials used in valves and why we do not use other materials
- Ans.
Valves are made of materials that can withstand high pressure, temperature, and corrosive environments.
Materials used in valves include stainless steel, brass, bronze, and plastic.
Stainless steel is commonly used due to its strength, durability, and resistance to corrosion.
Brass and bronze are used for their excellent thermal conductivity and resistance to corrosion.
Plastic valves are used in applications where chemica...

Interview Preparation Tips
Experience: Core: Subjects mainly are in design aspects of mass transfer, heat transfer and fluid mechanics.
Tips: Be thorough with the fundamentals and going through the basic formulae .CFD will be useful.
Round: Group Discussion
Experience: Generally they look for understanding of the subject. And it doesn't matter whether one is defending or offending the topic all that matters is to make your presence felt and your points to be noted.And a general rule of thumb is never to start a group discussion, wait till all speak, note their points and names, so that you can raise their point with their name, which shows that you are attentive and their points will serve as impetus for you to speak further.
Round: Interview
Experience: 1 technical interview: (20-25 minutes)Heat Transfer, Mass Transfer, Fluid Mechanics, CRE are concepts testedBe strong in your basic fundamentals
Tips: Be cool and composed in your interviews
Focus on key areas of processes like Heat Transfer, Mass Transfer, CRE and Fluid MechanicsBe thorough with pumps and pump characteristics

- Q1. How does a tray function in a column
- Ans.
A tray functions in a column by providing a surface for the separation of different components in a process.
Trays are used in distillation columns to separate different components based on their boiling points.
They provide a large surface area for vapor-liquid contact, allowing for efficient separation.
Trays can have various designs, such as bubble cap trays or sieve trays, to enhance separation efficiency.
They can als...

- Q1. Explain All the laws of Thermodynamics
- Ans.
The laws of thermodynamics are fundamental principles governing energy and heat transfer in physical systems.
First Law: Energy cannot be created or destroyed, only transferred or converted.
Second Law: Heat naturally flows from hot to cold objects, and entropy tends to increase over time.
Third Law: As temperature approaches absolute zero, entropy approaches a minimum value.
Examples: A car engine converting fuel into mot...

- Q1. How is flow affected with change in velocity in a venturimeter.
- Ans.
Velocity change affects flow in a venturimeter.
As velocity increases, pressure decreases and vice versa.
Flow rate is directly proportional to the square root of pressure difference.
Venturimeter is used to measure flow rate in pipes.
Flow rate can be calculated using Bernoulli's equation.
- Q2. Which is better cstr/pfr for zero order reaction.
- Ans.
PFR is better for zero order reaction as it maintains constant concentration throughout the reactor.
PFR maintains constant concentration throughout the reactor
CSTR may result in concentration gradients
PFR is more efficient for zero order reactions
CSTR may be more suitable for reactions with changing rate constants
